Maximise Your Space with ERA Construction Solutions
A rear house extension is the most popular way London homeowners expand their living space without the cost and hassle of moving. Perfect for opening up your kitchen, creating a larger dining area, or adding a light-filled open-plan living room, a rear extension adds both functionality and long-term property value.
At ERA Construction Solutions, we have delivered dozens of rear extensions across London. With over 20 years of experience, our team combines expert craftsmanship, premium materials, and a stress-free process to bring your vision to life.
What Is a Rear Extension?
A rear extension is built at the back of your property, usually opening onto the garden. It’s ideal for families who want more room to cook, dine, and relax together. With the right design, features like large sliding doors and skylights flood the space with natural light, blending indoor comfort with outdoor living.
Benefits of a Rear Extension
Add Value to Your Home – On average, a professionally built rear extension can increase your property’s value by 15–20%.
Create More Living Space – Extend your kitchen, add a dining area, or create a family hub that works for your lifestyle.
Modern Design Features – Incorporate bi-fold or sliding glass doors, skylights, and premium finishes for a stylish, open-plan feel.
Cost-Effective Solution – Far more affordable than buying a larger property in London.
How Long Does It Take?
On average, a rear house extension takes 8–12 weeks to complete, depending on size and specification. At ERA Construction Solutions, we follow a clear weekly schedule, keeping you informed at every step – from demolition and steelwork to plumbing, electrics, and final decoration.
